PATENTED APR. 9', 199'? A TTORNBYS' or sinulzu liquid packing l6 toprevent Leahillc sockets and mating linuclilcs arc almfpre cral'ilycoated with pitch or asphalt prcparatory to laying the same intothcivall, and after the wall is roniplctcd the interior face thereof iscoated with a thin luyor of cenicnt, a quantity of the liquidccnncntbcing poured into the pocket 16 upon the pitch or asphalt to forma closure for said pockct.

in order to reinforce and tank, suitable rods or bands 17 are disposedat spaced intervals on lhc cxtorior walls of rods 17 bear againstexterior walls of the tank at the knuckles 7, so that when the tensionof the bands or rods are regulated by adjusting the nuts 20 the knuckleswill be forccd into engagement with the sockets, and

thereby cllectually prevent accidental dis-.

placement of the blocks.

By having portions of the bands spaced from the Wall in this manner italso permits expansion of the rcccssed ends of the blocks when the waterin the [unit freezes, While by having the frce ends of the arms 18hearing against the adjacent blocks szild arms are braced and' preventedfrom bending when the rods or bands are tightened.

if desired, a suitable door may be formed in the side Walls of the tankbelow-the auxiliary bottom by omitting one of the blocks or slaves, sothat a Water-supply pipe may be extended upwardly between the Walls ofthe standard 9 and through the auxiliary bottom of the tank forsupplying water to the latter.

In Fig. 6 of tho drawings there is illustrated a modified form of theinvention in which the auxiliary bottom and central supnort or standardare .disposed with the blocks 5, beingerected on a foundation of cement,mortar, or other suitable material 3 l, which is subsequently coatedwith a layer of cement 22 or with alayer of pitch covered with cement.

In Figs. 7 to 10, inclusive, there is illus* trated a furtheri'nodification in which the blocks are arranged to form a culvert orarched structure. there are provided a, plurality of s )sccd columns orsupports 23, preferably formed of substantially rectangular-shapedblocks 24, some of which are curved to form the arch or top of theculvert, as indicated at 25. The blocks 24 are rovided with alinedlongitudiholly-dispose channels or recesses 26, adapted to receive theadj acent ends of the blocks or stoves 5, as best shown in Figs. 7 and 8of the drawin s, the blocks 5 in tnis case being oblong-in rape anddisposed one about the other throughout the height of the arch orculvert. The exterior faces of the blocks In tl is form of the deviceforming the supports 23 are-also provided with grooves or channels 27,in which are scatcd reinforcing-bars 28, said bars being conncctcd tosimilar bars 29, engaging the interior faccsof the blocks byclamping-rods 3t), passing through plates or Washers 3t), and seated intransverse grooves 31, formed :in the abutting faces of the blocks 24,as shown. strengthen tho 1 in order to reinforce and strengthen thc sidewalls of thc culvert, suitable tic-rods I o2 arc thrczulcd throughopenings Si) in the blocks 2 1- and clamped in position by nuts 34. Alayer of mortar or cement 35 is placed within the channels 26 to protectthe bars 28 from the action of the elements, and the inner faces of thcblocks 5 are also preferably coated with a thin layer of liquid cement,in the manner before described. It will of course be understood that inconstructing thev culvert tho concuved and convexed faces of thebloclzsor staves 5 may be coated with pitch or asphalt in order to form a moreperfect union. between the several blocks, and thereby prevent leakage.

lzlaving thus described the invention, What is claimed is 1. In buildingconstruction, a plurality of blocks each having one longitudinal edgethereof convex and its opposite edge concave for the reception of theconvex portion of an adjacent block, said blocks being laid in circularform and arranged in superposed courses, and a binding-rod engaging theside Walls of the several blocks at convex ends thereof and spacedlaterally from the conr00 caved ends of the blocks.

2. In building construction, a plurality of blocks each having onelongitudinal edge thereof convcx and its opposite edge concave for thereception of the convex portion of an 105 adjacent block, said blocksbeing laid in circular form and arranged in superposed courses, atbinding-rod engaging the side alls of the several blocks at the convexends thereof and spaced laterally from the con- Ixo caved ends of saidblocks, and means for adjusting the tension of the rod to thereby forcethe convex end of one block to its seat in the concavity of the matingblock.

3. In building construction, a plurality of 1 15 blocks each having onelongitudinal edge thereof convex and its opposite edge concave for thereception of the convex portion of an adjacent block said bloclr beinglaid in circular form and disposed in superposed courses, clips havingperforated angular (lisposed arms the free ends of which bear againstthe blocks, threaded binding-rods passing through the perforation in thearms and engaging the Walls of the blocks at the 12 5 convex endsthereof said rods being spaced laterally from the concaved ends of theblocks, and nuts threaded on the binding Wires and adapted to engage theangular arms for adjusting the tension of said rods.

, blocks each having seems courses at one en of the wall, a central support ior'the diaphragm, and binding-rods emhracin the wall and bearingagainst the walls of t e blocks at the convex ends thereof,

vsaid rods being s aced laterally from the I concaved ends of t eblocks.

5. In building construction, a plurality of blocks each having onelongitudinal edge thereof convex and lts opposite edge concave for thereception'of the convex portion of an adjacent block, said block .beinglaid in superposed courses to form a circular wall, a diaphragminterposed between adjacent courses at one end of the wall and havin aplurality of reinforcing-rods embed ed therein and extending within thewall, a

liquid coating for the interior surface of the. wall, and binding-rodsembracing the extenor surface of the wall and bearlng against thewallsof the blocks at the convex ends thereof. i v i 6. In buildingconstruction, a plurality of blocks each having one longitudinal edgegig thereof convex and its opposite edge 'concave for the rece tion ofthe convex ortion of an adjacent h ock, said blocks eing laid insuperposed courses to form .a circular wall ainl. havin their matingedges covered with Waterproo material, a diaphragm interposed owerbetween the adjacent courses at the end of the Wall and provided With anannular shoulder spaced from said wall to form a pocket adapted toreceive a plastic material,

and a plurality of spaced binding-rods embracing the exterior'of thewall and hearing against the walls of the blocks at'the convex endsthereof.

In testimony that I claim the foregoing as my own I have hereto atfixedmy signature in the presence of two witnesses.
